Hello, my class are loving using this resource but I've hit a problem! I cannot access any of the files for lesson 4. I've downloaded and re-downloaded from the individual lesson and from the unit pack with the same results. As the previous three lessons have been instantly accessible I'm at a bit of a loss. Any tips? Thanks for your help.

Hi Briann,
I am really sorry to hear about this mistake, and I apologise if it has caused you any trouble. It will be changed shortly!

Thank you so much lovely resource team for sorting things out so quickly- it all looks great now and my little mechanical engineers will soon be preparing their prototypes. Thanks again for such a fab unit.

All of the documents in this zip file are corrupted. Is there any way this can be sorted out?

Hi again. The actual zip file downloads fine and opens but the majority of the documents in it are corrupted, with the exception of 'success criteria' and 'unit overview. The corrupted files will not open and will not extract from the zip. This is also the case for lesson 2.

Thanks so much! I have just tried opening the files now but it's still not working. Although I'm not sure whether you have corrected it yet. :) Could you comment back to confirm when it has been corrected? Thank you so much for doing this!

Hi there. Lesson 2 has been fixed but Lesson 4 still will not open. Could this be corrected? Thanks

Could I suggest that you re-download the pack to see if this fixes the problem? If you're still having trouble, please send an email over to info@twinkl.co.uk and we'll be able to have a look at this in more detail for you.
